I read about perf tool and I was interested in using in my RedHat.
On Ubuntu it is enough to call sudo apt-get install linux-tools-2.6.38-11.

What about RED HAT? I tried both:

yum install linux-tools
yum install perf

...but it doesn't work.

Do you know where I can get the source code so that I can compile it on my own?
Currently the YUM repository is pointing to a server having most packages we usually install, but maybe it is missing this package.

Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
